Rahu Kalam Outside India: Why the Timing Changes Every Day and Every City

Rahu kalam is one-eighth of YOUR day, between YOUR sunrise and sunset. Fixed weekday tables are only an approximation — here is how it actually works abroad.

The rule

Divide the time between local sunrise and sunset into eight equal parts. Rahu kalam is one specific segment per weekday — the 8th part-position on Sunday, 2nd on Monday, 7th on Tuesday, 5th on Wednesday, 6th on Thursday, 4th on Friday, 3rd on Saturday.

Why printed tables mislead abroad

A printed "Monday 7:30–9:00 AM" assumes a ~6 AM sunrise and 12-hour day — roughly true year-round near Chennai. In London the day swings from under 8 hours in December to over 16 in June: each of the eight segments swells and shrinks, and rahu kalam moves with it. A fixed table can be off by two hours or more.

Our city pages compute today's actual sunrise/sunset for your coordinates and derive rahu kalam from them — the times below are live, not tabulated.
